/*
 * Date: 23 October 2001
 *
 * SUMMARY: Testing regexps with the global flag set.
 * NOT every substring fitting the given pattern will be matched.
 * The parent string is CONSUMED as successive matches are found.
 *
 * From the ECMA-262 Final spec:
 *
 * 15.10.6.2 RegExp.prototype.exec(string)
 * Performs a regular expression match of string against the regular
 * expression and returns an Array object containing the results of
 * the match, or null if the string did not match.
 *
 * The string ToString(string) is searched for an occurrence of the
 * regular expression pattern as follows:
 *
 * 1.  Let S be the value of ToString(string).
 * 2.  Let length be the length of S.
 * 3.  Let lastIndex be the value of the lastIndex property.
 * 4.  Let i be the value of ToInteger(lastIndex).
 * 5.  If the global property is false, let i = 0.
 * 6.  If i < 0 or i > length then set lastIndex to 0 and return null.
 * 7.  Call [[Match]], giving it the arguments S and i.
 *     If [[Match]] returned failure, go to step 8;
 *     otherwise let r be its State result and go to step 10.
 * 8.  Let i = i+1.
 * 9.  Go to step 6.
 * 10. Let e be r's endIndex value.
 * 11. If the global property is true, set lastIndex to e.
 *
 *          etc.
 *
 *
 * So when the global flag is set, |lastIndex| is incremented every time
 * there is a match; not from i to i+1, but from i to "endIndex" e:
 *
 * e = (index of last input character matched so far by the pattern) + 1
 *
 * Thus in the example below, the first endIndex e occurs after the
 * first match 'a b'. The next match will begin AFTER this, and so
 * will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched.
